Sorry Jon, I should have pointed out the internals are the same from the piston head backwards, so the piston is the same and so is the spring and guides and rear end cross pin and end plug, the trigger set up is the same as on my Supersport Custom but is slightly different than a normal Supersport.
Yes you are correct about the loading area but I think people may have grasped that, as one is an underlever fixed barrel and the other a break barrel
